  • Publication number: 20240014058
    Abstract: An article transport vehicle of this disclosure includes a fall restricting device. A vehicle body of the article transport vehicle includes a first cover section, a second cover section, and a cover connecting section. The fall restricting device includes a pair of fall restricting members and a driving mechanism. The pair of fall restricting members each include a supported section, a pair of vertical extension sections, and a lower connecting section. The driving mechanism drives the pair of fall restricting members to move between a restricting position and a release position. At the restricting position, the pair of vertical extension sections overlap a stored article in a second direction view, and furthermore the lower connecting section overlaps the stored article in a vertical view. At the release position, the lower connecting section does not overlap the stored article in the vertical view.

  • Patent number: 11001259
    Abstract: Each transport vehicle is configured to perform a vehicle following control if an inter-vehicle distance to the transport vehicle traveling ahead becomes less than or equal to a predetermined distance, the vehicle following control being a control in which traveling state of the own transport vehicle is controlled in order to maintain constant the inter-vehicle distance to the transport vehicle traveling ahead based on traveling state information of the transport vehicle traveling ahead. Each transport vehicle is configured to terminate the vehicle following control if preparation of the own transport vehicle for arrival at a destination is initiated while the vehicle following control is being performed or if a travel direction of the own transport vehicle at a branching location is determined to be different from a travel direction of the transport vehicle traveling ahead at the branching location while the vehicle following control is being performed.
